ALLOY.

No Drawing.

T all whom it may concern: Be it known that we, EDWARD KIAM and Marriniw G. CoLLrNs. citizens of the United States of America, residing at borough of 5 Manhattan, city, county, and State of New York, and Scarsdale, county of 'lVestches ter, State of New York, respectively, have invented certain new and useful Improveients in Alloys, of which the following is a specification. I

This invention relates to alloys of the semi-precious metal type.

An object of this invention is to provide a metal composition as a substitute for semi-precious metals and which is ductile, capable of being rolled into sheets and also capable of being formed into wire.

Pursuant to our invention, magnesium, platinum, gold and nickel are alloyed with 20 one another, in proportional parts increasing in the order of the metals named.

The proportion of magnesium is relatively low and may be varied within the range of from gram to 5 grams per each one pound, i. e., .453 kilogram, of resulting alloy mixture.

The proportion of platinum is higher than that of magnesium and per one pound, i. e., .453 kilogram, of resulting alloy mix- 30 'ture the platinum ranges from 5 grams to grams.

The gold ingredient is supplied usually in the form of 18 karat gold and the range of the gold ingredient is from 4 grams to 16 grams.

The nickel ingredient is preferably added in the form of pure nickel and of a range of proportion of from 300 grams to 400 grams.

Application filed July 8, 1922. Serial No. 573,733.

The resulting alloy possesses the properties of semi-precious metals and is eminently adapted for use in the jewelry and the dental trades.

The alloy is ductile and can be readily rolled into sheets.

The alloy is readily rolled and drawn into wire.

lVhereas we have described our invention by reference to specific forms thereof it will be understood that many changes and modifications may be made without departing from the spirit of the invention.

We claim:.

1. An alloy comprising magnesium. platinum, gold and nickel, in proportional parts increasing in the aforesaid order of the aforesaid ingredients, the content of nickel being largely predominant.

2. An alloy comprising magnesium in the proportion of fromi} gram to 5 grams; platinum in the proportion of from 5 grams to 20 grams; gold in the proportion of from 1- grams to 16 grams; and nickel in the proportion of from 300 grams to 400 grams.

3. An alloy of substantial freedom from impurity comprising magnesium 'in the proportion of from 9} gram to 5 grams; platinum in proportion of from 5 grams to 20 grams; gold of substantially 18 karat in the proportion of from 4 grams to 16 grams; and nickel in the proportion from 300 grams to 400 grams.

In testimony whereof we have signed this specification this 22nd day of June, 1922.
